Monologue \ Logger class not found, installation error in Laravel 4

Question

I installed Laravel without using composer by typing the following command:

C: \ wamp \ www \ travail> new laravel project

It seems like a good thing.

Creating an application ...

The application is ready! Build something awesome.

But when I tried to open my project here:

WAMP → local → unkind → project → public

I got this error:

Class "Monologue \ Logger" not found

• Check the value minimum-stabilityin the composer.json file and set it to stable:

  "minimum-stability": "stable"

  composer self-update

  composer update
